No time to give your strands the full salon treatment? Use a headband, like Jessica Biel's edgy spiked version, to sweep your hair back, then loosely wrap random sections around a curling iron to create a subtle wave.

While some have trouble styling their short cuts, a pixie crop is actually one of the most versatile 'dos out there! A fun hair accessory, like Michelle Williams's, is a low-maintenance way to change up the gamine style.

If you're in need of a new 'do but are short on time, switch up your part like Rose Byrne. We like how the swoop over her bangs makes a statement without channeling the extreme side parts of the '80s. If you normally part your hair to the side, section it in the other direction, or even in the middle to change up your look. If your strands are usually split in the center, a deep side part gives your hair a modern twist.

Sometimes when you're short on time, the night holds the key. Try curling your hair before heading to bed, and by morning, the tightly-wound curls will have fallen into sultry waves like Selita Ebanks's.
